SPRAY DEVICE Filed Sept. 25, 1956 INVENTOR ATTORNEYS Patented Oct. 26,1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to spray devices especially adapted for papermaking machines and has for the primary object the provision of a deviceof this character which is capable of discharging V fluid over a largerarea than accomplished by a fixed spraying device now in use and permitsa fewer number of spray nozzles or jets to be employed so as to conservefluid and render the operation of the device less expensive and topossess a maximum amount of efliciency.

With these and other objects in view, this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa side elevation illustrating a spray device constructed in accordancewith my invention.

Figure 2 is a fragmentary vertical sectional view illustrating theslidably mounted spray nozzle adapted for reciprocation during thedischarge of the fluid.

Figure 3 is a transverse sectional View taken on the line 3-3 of Figure2.

Figure 4 is a plan view of one of the supporting discs.

Figure 5 is a transverse sectional view illustrating one of the spraynozzles and its connection with a slidable fluid supply medium.

Referring in detail to the drawing, the numeral l indicates a tubularguide supported by members 2 and has formed in one wall thereof a slot 3which extends from end to end of said guide. A fluid distributing pipe 4extends into the guide and is arranged centrally thereof and is providedwith a series of nozzles or jets 5 which protrude through the slot 3.The fluid distributing pipe 4 is adapted for reciprocation and isslidably supported by disc-like elements 6, the latter being fixedthereto and engage the inner walls of the guide I. The elements 6 haveformed thereon projections 1 received in the slot 3 to prevent rotationof the pipe 4 during its sliding movement and to prevent the nozzles orjets from dragging against the walls of the slot 3.

A fluid supply pipe is shown at 8 and is connected to the distributingpipe 4 by a flexible pipe 9. A control valve I0 is located between theflexible pipe 9 and the supply pipe 8. The connecting rod H is pivotedto one end of the distributing pipe 4 and is eccentrically pivoted to apower pulley wheel [2 whereupon the rotation of said pulley wheel willbring about reciprocation of the fluid distributing pipe 4 andconsequently permit fluid to be sprayed over a comparatively large areaby the nozzles or jets 5 sliding back and forth with respect to saidarea.

Having described the invention, I claim:

1. A slidable spraying device comprising a tubular guide having a slotextending the full length thereof, supporting means for said guide, afluid distributing member located centrally of said guide, nozzlesconnected to said member and extending through the slot, discs securedto said member and engaging the guide, projections on said discs andextending into the slot, and means for reciprocating said member, andmeans for admitting fluid under pressure to said member.

2. A slidable spraying device comprising a tubular guide having a slotextending the full length thereof, supporting means for said guide, afluid distributing member located centrally of said guide, nozzlesconnected to said member and extending through the slot, discs securedto said member and engaging the guide, projections on said discs andextending into the slot, a power -means connected to one end of saidmember for the reciprocation thereof, a flexible pipe connected to saidmember, and a control valve connecting said flexible pipe to a fluidsupply pipe.

3. A slidable spraying device comprising a tubular guide having a slotextending the full length thereof, a reciprocal fluid distributingmember located centrally of said guide, means for slidably supportingsaid fluid distributing member in said guide, nozzles connected to saidfluid distributing member and extending through the slot, means forreciprocating said fluid distributing member, and means for admittingfluid under pressure to said member.
